Step-by-step explanation:
Socrates believed he provided a significant service to the city of Athens by fulfilling a divine mission to philosophize and seek the truth. He saw himself as a gadfly, stimulating the city to greater awareness of moral virtue and the welfare of the soul. His method of questioning leading citizens, exposing their lack of true knowledge, was aimed at encouraging critical thinking and virtue.

His legacy includes the philosophical foundations he laid down for Western thought and his role as a moral exemplar who prioritized ethical considerations over compliance with popular opinion.
